Why Docker?

Containers are one of the hottest technologies in software development in recent years, and Docker is by far the most popular tool for it. Containers enable leaner development and modern software architectures, like microservices. However, it sometimes needs to be clarified whether one should use containers and, if yes, how. In this course, you’ll learn through practical exercises to understand and use this exciting technology to your best benefit!


  • Strong understanding of the foundations of containers and Docker
  • Clear vision on what to use containers for, and what not
  • Ability to create own containers and use ready ones (Docker Hub)
  • Skill to combine containers into clusters with Docker Compose
  • Understand the software development process for containers

The most important goal is to get an excellent basic understanding that helps you to design software based on containers. It will be a solid foundation for further independent studies and exploration.
